QGIS actions - get currently selected attribute column (with python?)

Question

I'm trying to open files dynamically through actions. A simple example would be:

Action name: OpenLink

from PyQt4.QtCore import QUrl; 
from PyQt4.QtWebKit import QWebView;  

myWV = QWebView (None);
myWV.load(QUrl('[% "myColumn" %]')); myWV.show()

However this example is working with a fixed column name (myColumn). What I want to do is execute the action using whatever column in the object attributes I have selected.

Let's say I have three columns:

• mycolumn
• myColumn2
• myLink

when I right-click myLink, I would like to use the value from it in the above action. Is that possible?

You can use @current_field:

from PyQt4.QtCore import QUrl; 
from PyQt4.QtWebKit import QWebView;  

myWV = QWebView (None);
myWV.load(QUrl('[% @current_field %]')); myWV.show()
